When you add the block inside the curtin script you need to use the exact indent level the file already has otherwise curtin will ignore those commands.

why are these changes in this commit? config_maas.yml existed before the addition of console=, yes?

At the end I will just squash all my commits together, but you are right, I will try to separate my commits better in order to do this review process easier.
